Cyclodextrine Screening for the Chiral Separation of Carvedilol by Capillary Electrophoresis
Carvedilol is administered as a racemic mixture of the R(+)- and S(-)-enantiomers, although it was demonstrated that the two enantiomers exhibit different pharmacological effects and stereoselective pharmacokinetics. The aim of this study was the evaluation of several native and derivatized cyclodextrines as chiral selectors for the separation of carvedilol enantiomers. Stereoselective interact...
متن کاملIdentification and quantitation of cis-ketoconazole impurity by capillary zone electrophoresis-mass spectrometry.
trans-Ketoconazole was identified and quantified as impurity of cis-ketoconazole, an antifungal compound, by capillary zone electrophoresis-electrospray-mass spectrometry (CZE-ESI-MS). The chirality of this impurity was demonstrated separating their enantiomers by adding heptakis-(2,3,6-tri-O-methyl)-beta-cyclodextrin to the separation buffer in capillary electrophoresis (CE) with UV detection....
متن کاملChiral Analyses of Pollutants by Capillary Electrophoresis
The determination of enantiomeric composition of chiral xenobiotics and pollutants is a very difficult job due to their low amounts and poor detection by commonly used UV detector. But this sort of analysis is an important issue from the health point of view. The chiral analyses of these notorious pollutants by capillary electrophoresis have been discussed in this article. This review discusses...

متن کاملChiral Separation of Basic and Zwitterionic Drugs by Highly Sulfated Cyclodextrins Using Short-End Injection Capillary Electrophoresis Highly Sulfated Cyclodextrins Using Short-End Injection Capillary Electrophoresis
Due to high resolution power of sulfated cyclodextrins (HS-CDs), utilization of these selectors for chiral resolution of 7 basic and 2 zwitterionic drugs have been examined. Experiments were performed on a HP3DCE instrument equipped with an on-column diode array UV absorbance detector. Fused silica capillaries with an inner diameter of 50 ?m, an outer diameter of 365 ?m, and a total length of 4...
